Enviro-Clean 521

In a recent paper authored by Wan-Ning Lee et al, published in Food Chemistry ((2018) 256 319-326) UCT’s Enviro-Clean^® 521 solid phase extraction (SPE) cartridges were used to analyze 40 conventional and emerging DBPs in fresh cut produce wash water by modified EPA methods. The authors reported that good recoveries (60–130%) were achieved for most DBPs in deionized water and in lettuce, strawberry and cabbage wash water. The method detection limits are in the range of 0.06–0.58 μg/L for most DBPs and 10–24 ng/L for nitrosamines in produce wash water.
